Paper Abstract

The intracavity photon density and the initial population-inversion density are assumed to be Gaussian spatial distributions in the rate equations of a laser diode end-pumped passively Q-switched Nd:YVO4 laser with Cr4+:YAG saturable absorber. These space-dependent rate equations are solved numerically. In an experiment, such a laser has been realized. The dependences of pulse width, pulse repetition rate, single-pulse energy, and peak power on incident pump power were measured, and the experimental results are consistent with the numerical solutions.
